Daniel Eceizabarrena, Felipe Ponce-Vanegas

AI总结:

本文结合Bourgain反例的分形扩展与中间空间技巧,构造了分形Schrödinger收敛问题的反例,显式构造发散集并计算其Hausdorff维数,证实其达到了与加权$L^2$限制估计反例相同的正则性。

摘要:

我们结合Bourgain反例的分形扩展与Du--Kim--Wang--Zhang的中间空间技巧,构造了分形Schrödinger收敛问题的反例。我们证实,该收敛问题实现了与Du关于加权$L^2$限制估计的反例相同的正则性。为此,我们需显式构造发散集并计算其Hausdorff维数,为此我们使用了源自Diophantine逼近的Mass Transference Principle。

英文摘要:

We construct counterexamples for the fractal Schrödinger convergence problem by combining a fractal extension of Bourgain's counterexample and the intermediate space trick of Du--Kim--Wang--Zhang. We confirm that the same regularity as Du's counterexamples for weighted $L^2$ restriction estimates is achieved for the convergence problem. To do so, we need to construct the set of divergence explicitly and compute its Hausdorff dimension, for which we use the Mass Transference Principle, a technique originated from Diophantine approximation.
